Hello,
I am trying to convert a tall array with a column of strings to numbers. I tried this:
ds = datastore(fullfile(p,'tallFinal.csv'));
ds.SelectedFormats={'%q','%C','%C','%s'};
ds.VariableNames = {'DATE','TICKER','FIELD','VALUE'};
tds = tall(ds);
tmp = str2double(tds.VALUE);
[tds.fVALUE]=gather(tmp);
And recieved an error after over two hours of processing.
Evaluating tall expression using the Parallel Pool 'local':
- Pass 1 of 2: Completed in 10 min 50 sec
- Pass 2 of 2: Completed in 2 hr 11 min
Evaluation completed in 2 hr 22 min
In expressions of the form T.X = B where T is a tall table, B must be a tall array.
Thank You,
Michael
